Friction disc with surface pattern



FIG. 1 is a front view of a first embodiment of a friction disc with surface pattern;

FIG. 2 is a side view of the design of FIG. 1 showing that the features on the front of the design are also applied to the rear;

FIG. 3 is a front view of a second embodiment of a friction disc with surface pattern; and,

FIG. 4 is a perspective view of the design of FIG. 3.

The ornamental design includes surface texturing formed by embossed or debossed features having a trailing edge with a V-shape in friction material of a friction disc to give the appearance of a pattern of rows spiraling in a common clockwise or counterclockwise direction, the V-shape trailing edge defining an interior boundary of the design.

The dot-dash-dot broken line immediately adjacent to the interior solid line is the boundary of the claim and forms no part thereof. The broken line and areas within the broken line boundary depict portions of the friction disc with surface pattern that form no part of the claimed design. 

CLAIM The ornamental design for a friction disc with surface pattern, as shown and described.
